Here's a step-by-step plan for creating the model to classify news articles into one of the eight possible labels.
- Install necessary libraries and set environment variables:
pythonCopy code!pip install kaggle
!pip install wandb==0.14.0
!pip install pytorch-lightning==1.9.4
!pip install torch==1.13.0
import os
os.environ["TOKENIZERS_PARALLELISM"] = "false"
os.environ["CUDA_LAUNCH_BLOCKING"] = "1"
- Define
my_config
:
pythonCopy codemy_config = {
'project_name': 'ChatGPT-prompt',
'model_name': 'microsoft/deberta-v3-large',
'num_workers': 4, # adjust as needed
'num_labels': 8,
'max_epochs': 5,
'max_length': 256,
'batch_size': 16,
'accumulate_grad_batches': 4,
'warmup_steps': None, # to be set later
'wandb_api_key': '93460ff86561b201141546a407885ba3c8318d81',
'data_dir': '/kaggle/input/pp-dataset/',
'result_dir': 'kaggle/working/result'
}
- Define dataset class:
pythonCopy codefrom torch.utils.data import Dataset
class NewsDataset(Dataset):
def __init__(self, df, tokenizer, max_length, train_or_test='train'):
self.df = df
self.tokenizer = tokenizer
self.max_length = max_length
self.train_or_test = train_or_test
def __len__(self):
return len(self.df)
def __getitem__(self, idx):
text = self.df.loc[idx, 'text']
inputs = self.tokenizer(text, max_length=self.max_length, padding='max_length', truncation=True, return_tensors='pt')
if self.train_or_test == 'train':
label = self.df.loc[idx, 'label']
return {'input_ids': inputs['input_ids'].squeeze(), 'attention_mask': inputs['attention_mask'].squeeze(), 'labels': label}
else:
return {'input_ids': inputs['input_ids'].squeeze(), 'attention_mask': inputs['attention_mask'].squeeze()}
- Define datamodule:
pythonCopy codefrom pytorch_lightning import LightningDataModule
from sklearn.model_selection import train_test_split
from torch.utils.data import DataLoader
from imblearn.over_sampling import RandomOverSampler
class NewsDataModule(LightningDataModule):
def __init__(self, config, tokenizer):
super().__init__()
self.config = config
self.tokenizer = tokenizer
self.batch_size = config['batch_size']
self.num_workers = config['num_workers']
def prepare_data(self):
# Load train and test data
self.train_df = pd.read_csv(os.path.join(self.config['data_dir'], 'pp_train.csv'))
self.test_df = pd.read_csv(os.path.join(self.config['data_dir'], 'pp_test.csv'))
def setup(self, stage=None):
# Split train data into train and validation
train_data, val_data = train_test_split(self.train_df, test_size=0.2, random_state=43, stratify=self.train_df['label'])
# Apply RandomOverSampler
ros = RandomOverSampler(random_state=43)
X_resampled, y_resampled = ros.fit_resample(train_data[['id', 'text']], train_data['label'])
# Create datasets
self.train_dataset = News
keep going
Dataset(X_resampled, self.tokenizer, self.config['max_length'], 'train') self.val_dataset = NewsDataset(val_data, self.tokenizer, self.config['max_length'], 'train') self.test_dataset = NewsDataset(self.test_df, self.tokenizer, self.config['max_length'], 'test')
pythonCopy codedef train_dataloader(self):
return DataLoader(self.train_dataset, batch_size=self.batch_size, num_workers=self.num_workers, shuffle=True)
def val_dataloader(self):
return DataLoader(self.val_dataset, batch_size=self.batch_size, num_workers=self.num_workers)
def test_dataloader(self):
return DataLoader(self.test_dataset, batch_size=self.batch_size, num_workers=self.num_workers)
pythonCopy code
5. Define PyTorch Lightning classification model:
```python
import pytorch_lightning as pl
from transformers import AutoModelForSequenceClassification, AutoTokenizer, AutoConfig, AdamW
from sklearn.metrics import f1_score
class NewsClassifier(pl.LightningModule):
def __init__(self, config):
super().__init__()
self.config = config
self.model = AutoModelForSequenceClassification.from_pretrained(config['model_name'], num_labels=config['num_labels'])
def forward(self, input_ids, attention_mask):
return self.model(input_ids=input_ids, attention_mask=attention_mask)
def training_step(self, batch, batch_idx):
outputs = self(batch['input_ids'], batch['attention_mask'])
loss = outputs.loss
return {'loss': loss}
def validation_step(self, batch, batch_idx):
outputs = self(batch['input_ids'], batch['attention_mask'])
loss = outputs.loss
logits = outputs.logits.argmax(dim=1)
f1 = f1_score(batch['labels'].cpu(), logits.cpu(), average='macro')
return {'val_loss': loss, 'val_f1_score': f1}
def test_step(self, batch, batch_idx):
outputs = self(batch['input_ids'], batch['attention_mask'])
logits = outputs.logits.argmax(dim=1)
return {'id': batch['id'], 'label': logits}
def test_epoch_end(self, outputs):
# Generate submission CSV
ids = []
labels = []
for out in outputs:
ids.extend(out['id'].tolist())
labels.extend(out['label'].tolist())
submission = pd.DataFrame({'id': ids, 'label': labels})
submission.to_csv(os.path.join(self.config['result_dir'], 'submission_debertav3.csv'), index=False)
def configure_optimizers(self):
optimizer = AdamW(self.parameters(), lr=2e-5)
return optimizer
- Set up training, logging, and callbacks:
pythonCopy codefrom pytorch_lightning.callbacks import EarlyStopping, ModelCheckpoint, LearningRateMonitor
from pytorch_lightning.loggers import WandbLogger
# Create tokenizer
tokenizer = AutoTokenizer.from_pretrained(my_config['model_name'])
# Create dataset
dm = NewsDataModule(my_config, tokenizer)
dm.prepare_data()
dm.setup()
# Set warmup_steps
my_config['warmup_steps'] = (len(dm.train_dataloader()) * my_config['max_epochs']) // 5
# Set up logger and callbacks
wandb_logger = WandbLogger(project=my_config['project_name'], api_key=my_config['wandb_api_key'])
early_stopping = EarlyStopping(monitor='val_f1_score', mode='max', patience=1)
checkpoint_callback = ModelCheckpoint(monitor='val_f1_score', mode='max', save_top_k=1, dirpath=my_config['result_dir'], filename='best_model')
lr_monitor = LearningRateMonitor(logging_interval='step
keep going
pythonCopy code
7. Set up Trainer and start training:
```python
# Create Trainer
trainer = pl.Trainer(
logger=wandb_logger,
gpus=1,
max_epochs=my_config['max_epochs'],
callbacks=[early_stopping, checkpoint_callback, lr_monitor],
precision=16,
accumulate_grad_batches=my_config['accumulate_grad_batches'],
stochastic_weight_avg=True
)
# Train the model
news_classifier = NewsClassifier(my_config)
trainer.fit(news_classifier, dm)
# Test the model
trainer.test(news_classifier, datamodule=dm)
With this setup, you can train a DeBERTa-v3 model for classifying news articles using the given dataset. This will also generate the submission file, submission_debertav3.csv
, with the predicted labels for the test dataset.
Keep in mind that this is just one example, and there are many ways to fine-tune and optimize the model, such as by adjusting hyperparameters, experimenting with different model architectures, or using additional techniques like transfer learning or data augmentation.

It seems like the issue is occurring in the __getitem__
method of the NewsDataset
class when trying to access the dataframe using self.df.loc[idx, 'text']
. This error may be caused by the DataFrame not being indexed properly. To resolve this issue, you can reset the index of the DataFrame before using it in the Dataset class.
In the NewsDataModule
class, after applying the RandomOverSampler and creating the new resampled DataFrame, reset the index for X_resampled
, val_data
, and self.test_df
:
pythonCopy codeX_resampled.reset_index(drop=True, inplace=True)
val_data.reset_index(drop=True, inplace=True)
self.test_df.reset_index(drop=True, inplace=True)
Add these lines of code inside the setup
method of the NewsDataModule
class after the RandomOverSampler:
pythonCopy codedef setup(self, stage=None):
# Split train data into train and validation
train_data, val_data = train_test_split(self.train_df, test_size=0.2, random_state=43, stratify=self.train_df['label'])
# Apply RandomOverSampler
ros = RandomOverSampler(random_state=43)
X_resampled, y_resampled = ros.fit_resample(train_data[['id', 'text']], train_data['label'])
# Reset the index
X_resampled.reset_index(drop=True, inplace=True)
val_data.reset_index(drop=True, inplace=True)
self.test_df.reset_index(drop=True, inplace=True)
# Create datasets
...
This should resolve the KeyError and allow the DataLoader to access the data correctly.
이런 과정이 왜 필요한거야?
데이터 프레임의 인덱스 문제로 인한 KeyError가 발생했기 때문에, 인덱스를 재설정하는 과정이 필요합니다. 데이터 전처리 및 샘플링 과정에서 원본 데이터의 인덱스가 변경되거나 누락될 수 있습니다. 이로 인해 DataLoader가 데이터를 올바르게 읽지 못할 수 있습니다.
인덱스를 재설정하는 이유는 다음과 같습니다:
데이터 프레임을 올바르게 읽기 위해:
__getitem__
메소드에서self.df.loc[idx, 'text']
를 사용하여 데이터 프레임의 특정 행을 가져오려고 했습니다. 그러나 데이터 프레임의 인덱스가 불연속적이거나 변경되었기 때문에 KeyError가 발생했습니다. 인덱스를 재설정하면 이러한 문제를 해결하고 DataLoader가 데이터를 올바르게 읽을 수 있습니다.데이터 샘플링 과정에서 인덱스 불일치 방지: 데이터를 분할하거나 오버 샘플링을 사용하면 원본 데이터 프레임의 인덱스가 변경되거나 일부 인덱스가 누락될 수 있습니다. 이로 인해 인덱스가 불연속적이거나 일치하지 않을 수 있습니다. 인덱스를 재설정하면 데이터 프레임의 인덱스가 연속적이고 일관된 상태가 유지되어 이후의 데이터 처리 과정에서 문제가 발생하지 않습니다.
요약하면, 인덱스를 재설정하는 과정은 데이터 프레임의 인덱스 문제를 해결하고 DataLoader가 데이터를 올바르게 읽을 수 있도록 하는 데 필요합니다. 이 과정은 데이터 전처리 및 샘플링 과정에서 발생할 수 있는 인덱스 불일치 문제를 해결하는 데 도움이 됩니다.
/opt/conda/lib/python3.7/site-packages/pandas/core/indexes/base.py in get_loc(self, key, method, tolerance) 3361 return self._engine.get_loc(casted_key) 3362 except KeyError as err: -> 3363 raise KeyError(key) from err 3364 3365 if is_scalar(key) and isna(key) and not self.hasnans: KeyError: 'label'
This KeyError suggests that the 'label' column is missing in the DataFrame when it is trying to be accessed. It is important to ensure that the 'label' column is available in the DataFrame when it is required.
Looking back at the code, I see that this issue may occur during the test dataset processing. In the NewsDataModule
class, you've mentioned that the test dataset doesn't have a 'label' column, but you're not handling this situation in the NewsDataset
class.
To fix this issue, you need to modify the __getitem__
method of the NewsDataset
class to handle the case when the 'label' column is not available (i.e., when processing the test dataset).
Here's an updated version of the __getitem__
method:
pythonCopy codedef __getitem__(self, idx):
text = self.df.loc[idx, 'text']
input_ids, attention_mask = self.tokenize(text)
if self.train_or_test == 'test':
return {
'id': self.df.loc[idx, 'id'],
'input_ids': torch.tensor(input_ids, dtype=torch.long),
'attention_mask': torch.tensor(attention_mask, dtype=torch.long)
}
else:
label = self.df.loc[idx, 'label']
return {
'input_ids': torch.tensor(input_ids, dtype=torch.long),
'attention_mask': torch.tensor(attention_mask, dtype=torch.long),
'labels': torch.tensor(label, dtype=torch.long)
}
With this update, the code checks whether it is processing the test dataset or not. If it's the test dataset, it doesn't try to access the 'label' column and returns only the 'id', 'input_ids', and 'attention_mask'. Otherwise, it returns 'input_ids', 'attention_mask', and 'labels' as before. This should resolve the KeyError.
X_resampled, y_resampled = ros.fit_resample(train_data[['id', 'text']], train_data['label']) # Reset the index X_resampled.reset_index(drop=True, inplace=True) y_resampled.reset_index(drop=True, inplace=True) val_data.reset_index(drop=True, inplace=True) self.test_df.reset_index(drop=True, inplace=True) # Create datasets self.train_dataset = NewsDataset(X_resampled, self.tokenizer, self.config['max_length'], 'train') i guess you need to gather up x_resampled with y_resampled
You're right. I apologize for the oversight. After resampling the data using the RandomOverSampler, you need to concatenate X_resampled
and y_resampled
to create a new DataFrame with both the text and label columns. You can do this using the pd.concat
function:
pythonCopy code# Concatenate X_resampled and y_resampled
resampled_data = pd.concat([X_resampled, y_resampled], axis=1)
Then, update the DataFrame passed to the NewsDataset
class for the train dataset:
pythonCopy codeself.train_dataset = NewsDataset(resampled_data, self.tokenizer, self.config['max_length'], 'train')
Here's the updated setup
method for the NewsDataModule
class:
pythonCopy codedef setup(self, stage=None):
# Split train data into train and validation
train_data, val_data = train_test_split(self.train_df, test_size=0.2, random_state=43, stratify=self.train_df['label'])
# Apply RandomOverSampler
ros = RandomOverSampler(random_state=43)
X_resampled, y_resampled = ros.fit_resample(train_data[['id', 'text']], train_data['label'])
# Concatenate X_resampled and y_resampled
resampled_data = pd.concat([X_resampled, y_resampled], axis=1)
# Reset the index
resampled_data.reset_index(drop=True, inplace=True)
val_data.reset_index(drop=True, inplace=True)
self.test_df.reset_index(drop=True, inplace=True)
# Create datasets
self.train_dataset = NewsDataset(resampled_data, self.tokenizer, self.config['max_length'], 'train')
self.val_dataset = NewsDataset(val_data, self.tokenizer, self.config['max_length'], 'valid')
self.test_dataset = NewsDataset(self.test_df, self.tokenizer, self.config['max_length'], 'test')
Now, the train dataset should have both the text and label columns, which should resolve any issues when creating and using the NewsDataset
object.
OutOfMemoryError: CUDA out of memory. Tried to allocate 64.00 MiB (GPU 0; 15.90 GiB total capacity; 14.95 GiB already allocated; 39.75 MiB free; 15.01 GiB reserved in total by PyTorch) If reserved memory is >> allocated memory try setting max_split_size_mb to avoid fragmentation. See documentation for Memory Management and PYTORCH_CUDA_ALLOC_CONF
The OutOfMemoryError
indicates that your model is running out of GPU memory during training. This can be caused by the model size, batch size, or input sequence length. There are several ways to address this issue:
- Reduce the batch size: Lowering the batch size will reduce the GPU memory consumption, but it may also affect the model's performance. Update the
my_config
dictionary with a smaller batch size:
pythonCopy codemy_config = {
...
'batch_size': 8, # or even lower, depending on your GPU memory
...
}
- Reduce the maximum input sequence length: If your input sequences are very long, you can truncate or reduce the maximum input sequence length to save GPU memory. Update the
my_config
dictionary with a smaller max length:
pythonCopy codemy_config = {
...
'max_length': 128, # or an appropriate length based on your data
...
}
- Enable mixed-precision training: Using mixed-precision training can help reduce memory consumption without significantly affecting model performance. Update the
Trainer
initialization with theprecision
argument:
pythonCopy codetrainer = pl.Trainer(
...
precision=16, # Enables mixed-precision training
...
)
- Gradient accumulation: You can accumulate gradients over multiple batches before updating the model weights. This allows you to effectively increase the batch size without increasing memory consumption. Update the
my_config
dictionary with the appropriateaccumulate_grad_batches
value:
pythonCopy codemy_config = {
...
'accumulate_grad_batches': 8, # or a different value, depending on your needs
...
}
- Use a smaller model: If you still face memory issues, consider using a smaller version of the model. For example, you can try using
microsoft/deberta-v3-base
instead ofmicrosoft/deberta-v3-large
. Update themy_config
dictionary with the smaller model:
pythonCopy codemy_config = {
...
'classification_model_name': 'microsoft/deberta-v3-base',
...
}
Try these approaches one by one or in combination until your model fits within the available GPU memory. Keep in mind that making changes to the configuration may affect the performance of your model, so you may need to fine-tune the hyperparameters accordingly.
MisconfigurationException: In automatic_optimization, when `training_step` returns a dict, the 'loss' key needs to be present
This error occurs because PyTorch Lightning expects a key called 'loss' in the dictionary returned by the training_step
method when using automatic optimization. To fix this issue, simply change the key 'loss' in the dictionary returned by training_step
.
Here's an example of how to update the training_step
method in your model:
pythonCopy codedef training_step(self, batch, batch_idx):
outputs = self(**batch)
loss = outputs.loss
self.log('train_loss', loss, prog_bar=True, on_step=True, on_epoch=True)
return {'loss': loss} # Make sure to use the key 'loss' here
By returning a dictionary with the key 'loss', PyTorch Lightning will recognize the loss value correctly and perform automatic optimization as expected.
이미 key를 제대로 넣고 있어
I apologize for the confusion. In that case, let's review your training_step
method to identify any issues. Please share the code for the training_step
method in your PyTorch Lightning model. I'll be able to provide further guidance after examining your implementation.
def training_step(self, batch, batch_idx): outputs = self(batch['input_ids'], batch['attention_mask']) loss = outputs.loss return {'loss': loss}
My apologies for the confusion earlier. Your training_step
method looks correct.
However, there's a possibility that the loss
attribute might not be available in the outputs
object. This can happen if you're not passing the labels
to your model during training. When using Hugging Face transformers, you need to pass the labels
to the model so that it can calculate the loss internally.
Here's the updated training_step
method:
pythonCopy codedef training_step(self, batch, batch_idx):
outputs = self(
input_ids=batch['input_ids'],
attention_mask=batch['attention_mask'],
labels=batch['labels'] # Pass the labels to the model
)
loss = outputs.loss
return {'loss': loss}
By passing the labels
to the model, it should now be able to calculate the loss and return it in the outputs
object.
class NewsClassifier(pl.LightningModule): def __init__(self, config): super().__init__() self.config = config self.model = AutoModelForSequenceClassification.from_pretrained(config['model_name'], num_labels=config['num_labels']) def forward(self, input_ids, attention_mask): return self.model(input_ids=input_ids, attention_mask=attention_mask) def training_step(self, batch, batch_idx): outputs = self(batch['input_ids'], batch['attention_mask']) loss = outputs.loss return {'loss': loss} def validation_step(self, batch, batch_idx): outputs = self(batch['input_ids'], batch['attention_mask']) loss = outputs.loss logits = outputs.logits.argmax(dim=1) f1 = f1_score(batch['labels'].cpu(), logits.cpu(), average='macro') return {'val_loss': loss, 'val_f1_score': f1} def test_step(self, batch, batch_idx): outputs = self(batch['input_ids'], batch['attention_mask']) logits = outputs.logits.argmax(dim=1) return {'id': batch['id'], 'label': logits} def test_epoch_end(self, outputs): # Generate submission CSV ids = [] labels = [] for out in outputs: ids.extend(out['id'].tolist()) labels.extend(out['label'].tolist()) submission = pd.DataFrame({'id': ids, 'label': labels}) submission.to_csv(os.path.join(self.config['result_dir'], 'submission_debertav3.csv'), index=False) def configure_optimizers(self): optimizer = AdamW(self.parameters(), lr=2e-5) return optimizer
Thank you for sharing the code. I noticed that the labels
are not being passed to the model in the forward
method. You should update the forward
method to include the labels
argument and pass it to the model. Here's the updated code:
pythonCopy codeclass NewsClassifier(pl.LightningModule):
def __init__(self, config):
super().__init__()
self.config = config
self.model = AutoModelForSequenceClassification.from_pretrained(config['model_name'], num_labels=config['num_labels'])
def forward(self, input_ids, attention_mask, labels=None):
return self.model(input_ids=input_ids, attention_mask=attention_mask, labels=labels)
def training_step(self, batch, batch_idx):
outputs = self(batch['input_ids'], batch['attention_mask'], batch['labels'])
loss = outputs.loss
return {'loss': loss}
...
By including the labels
in the forward
method, the model should now be able to calculate the loss and return it in the outputs
object.
thanks!
You're welcome! If you have any more questions or need further assistance, feel free to ask. Good luck with your project!
몇가지 고칠 점이 있어. 1. learningrate가 너무 높아 6e-6로 하고 my_config에 넣어줘 2. batch_size도 4로 수정해줘
Sure, I can help you make those changes. Here's the updated my_config
dictionary and the configure_optimizers
method in the NewsClassifier
class:
- Update the learning rate in
my_config
:
pythonCopy codemy_config = {
...
'lr': 6e-6, # Set learning rate to 6e-6
'batch_size': 4, # Set batch size to 4
...
}
- Update the
configure_optimizers
method in theNewsClassifier
class to use the learning rate frommy_config
:
pythonCopy codeclass NewsClassifier(pl.LightningModule):
...
def configure_optimizers(self):
optimizer = AdamW(self.parameters(), lr=self.config['lr'])
return optimizer
By making these changes, your model will now use a learning rate of 6e-6 and a batch size of 4 during training.
그리고 test_epoch_end에서 label이 device에 올라가 있어서 안돼. cpu로 돌려서 csv를 만드는 과정을 완성해줘 id는 to list할 필요가 없어 이미 list이기 때문에
Sure, I'll modify the test_epoch_end
method to move the label
to the CPU before generating the CSV file. Here's the updated code:
pythonCopy codedef test_epoch_end(self, outputs):
# Generate submission CSV
ids = []
labels = []
for out in outputs:
ids.extend(out['id'])
labels.extend(out['label'].cpu().tolist()) # Move the label to the CPU before converting to a list
submission = pd.DataFrame({'id': ids, 'label': labels})
submission.to_csv(os.path.join(self.config['result_dir'], 'submission_debertav3.csv'), index=False)
By updating the test_epoch_end
method in this way, the label
will be moved to the CPU before being converted to a list and used for generating the CSV file.
